So, is this supposed to happen on "any" device using DVI when doing this xrandr
query? Would xorg crawl to a halt on AMD or Intel if you use `for x in

If such a spammy function would never ever happen on any linux program other
than wine, i can see it not being fixed by upstream driver tho, and finding a
better solution in wine is needed (as you point out)... however, if only nVidia
GPU's would exhibit this kind of behaviour if this particular for sequence is
used, perhaps it is a driver issue someone should consider bugreporting? 

It does seem as the proposed fix forces 32bpp, and bypass some sort of
detection (that seemingly does not work to well on nVidia with DVI + multiple
displays).

I don't have a DVI port on my RTX card, so i cant really do any testing i
guess.
